Hi all. When looking at engine strength, is a higher cc rating a stronger engine (for example 25 cc vs. 31 cc) or is the lower cc stronger, like the lower the wire gauge, the thicker it is? Thanks for any help.
It is difficlut to say which is stronger, but the larger number makes for a bigger motor. The cc is cubic centimeters. Just like cubic inches only in the meteric system. You would usually think the bigger number would make for more horsepower but maybe not.
yes, this is generally the rule

Larger number is generally better as it means more displacement (cubic centimeters). While it is true in most cases, there will always be an exception. Which is more powerful, a big V-8 or a tiny four cylinder engine? There are plenty of smaller displacement 4 cylinder engines that put out more power than a big V-8. Just look at most Indy cars.
Once you have the engine size, you have to know what to do with it in terms of carburetion, exhaust tuning, valving, etc.
Hi, Hope you're not a troll. Higher no. means bigger eingine but not necessarily stronger some cases. It all depends how it is designed. Tony

Strictly speaking, under controlled conditions and only varying the number of cc's, the large cc's has the most power. That's what I think you're asking.
Usually the larger the number of cc's (cubic centimeters), the more power as long as you are comparing apples to apples. eg a 30 cc weed trimmer won't have the working power of a 50 cc weed trimmer of the same type and design.
But, taking a 100 cc engine from one place and installing it in another place, to replace say a 75cc engine won't necessarily translate to more power delivered to the load. Too many variables, plus what others have mentioned when you get deeper into it.
If you're comparing a B&S engine to say a Tecumseh, the same cc engine in each will not necessarily deliver the same power so a few cc difference isn't much of an indicator. Magnitudes of cc's change though are pretty sure that the higher cc engine will have the more power in those two engines are they're close but NOT the same in design.
